.heicファイルとは？

HEIC (High Efficiency Image Container) is a modern image format used by Apple devices since iOS 11 and macOS High Sierra. HEIC files are based on the HEIF (High Efficiency Image Format) standard and use HEVC (H.265) compression, producing files that are roughly 50% smaller than equivalent JPEG images while maintaining the same or better visual quality. HEIC also supports features like image sequences, depth maps, and transparency.
